A spokesman for ​St. Louis County Prosecutor Robert McCulloch said he would not comment on reports that Ferguson police officer Darren Wilson suffered a fractured eye bone during Wilson’s confrontation with Michael Brown that ended with the officer shooting and killing the unarmed teen.

“We do not comment on any evidence in the case, and that would include the officer’s injuries,” said Ed Magee.

Magee said that prosecutors have not received any medical records relating to Wilson so far. ​But he said that since Wilson was taken to the hospital, they assume there are medical records and they just haven’t received them yet.

A family friend of Wilson’s told The Washington Post that Wilson suffered a fractured eye socket. Ferguson police have said that Wilson’s face was injured and he needed medical treatment, but they did not go into any detail. On Wednesday night, Ferguson Mayor James Knowles III told Fox News that he could not confirm reports that Wilson suffered a fractured eye bone.

Prosecutors have not been in direct contact with Wilson yet, Magee said. McCulloch has been in touch with Wilson’s attorney but has not spoken to Wilson himself.

Wilson will be given an opportunity to appear before the grand jury, but he cannot be compelled to appear, Magee said.

Prosecutors began presenting evidence to the St. Louis County grand jury on Wednesday. McCulloch said Wednesday that it could be mid-October before all of the evidence is presented, noting that not all of it is ready yet.

Since Brown was killed, authorities have provided relatively few details about the encounter between the teenager and Wilson. Ferguson Police Chief Thomas Jackson said last week that Wilson had a “swollen face” after the altercation and was taken to a hospital for treatment, but he did not provide any other information beyond saying the injuries were not life-threatening.

A day after Brown was shot, St. Louis County Police Chief Jon Bellmar told reporters that Brown “allegedly pushed” Wilson back into the car and physically assaulted him. Bellmar did not elaborate.

Dorian Johnson, 22, who was with Brown and said he witnessed the shooting, has claimed that Wilson instigated the confrontation, pulling up to the pair in his police cruiser and telling them to get out of the middle of the street.

Freeman Bosley Jr., Johnson’s attorney and a former St. Louis mayor, told The Washington Post that Wilson pulled up so close to Brown that when he opened his car door, it bumped into the teenager.

Bosley said Wilson reached out and grabbed Brown by the throat and grabbed his shirt as Brown tried to move away. At that point, Johnson said he saw Wilson pull out a gun and shoot Brown in the chest or arm. Johnson said the officer hit Brown with another round as he was running away and fatally gunned him down after he stopped and raised his hands in surrender.

Michael Brady, another witness, told CNN that he saw “some kind of tussle going on” with Wilson still inside the car and Brown next to it. Brady said Brown and Johnson then ran away, while Wilson got out of his car and began shooting.
